Letlers Patent No. 97,137, dated November 23, -1869.

IMPROVEMENT IN SEEDING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same,

ence heilig had to the accompanying drawings, form-v ing part of this specification, in which- Figure. 1 is a plan view.

Figure 2 is a side elevation. v

Figure 3 is a perspective vlewof seeding-cylimler.

Figure 4, vertical cross-section.

rlhe nat-ure of this invention has relation to a seeding-cylinder, constructed as clearly shown in iig. 3, and arranged to operate as shown in the other figures.

This cylinder is provided with a suitable hearing, A, and with seed-cups B, runninglengthwise, formed hy the radial flanges B, whose edges de not extend out as far as the periphery of the bearing A; that is, a circle, of which .these flanges would be the radii, would not be as large as the circumference of the bearing. 'O is the cap, covering said cylinder, andl D is the hanger bolted thereto, brming, together, a box, the bore of which is of a size with the bearing A, so that when the seeding-cylinder is therein, 'a space, B2, will be left between the edges of the radial anges Bl, and the inner surface or bore of the said box, for the purposef preventing the ,crushing ofthe seeds as the cylinder' revolvcs,while at the same time, by moving the cylinder on its shaft, in either direct-ion of its lengt-h, the quant-ity of seeds received into the cups and discharged, is regulated, the width of the space B2 being that left between the shoulder of the bearing A and slidinghead E.

lVhen the shoulder or" the bearing A is moved close up to the sliding head E, the cylinder is prevented from receiving or being charged with grain, and as the bearing lits closely within the box formed by the hanger and cap, no grain can escape between the bearing and bore ot' said box.

The cap C is provided with an opening, Gl, for the entrance of' grain to thel seed-cups B, on one Side of' the vertical diameter ofthecylind'er.

The opening C2, for the discharge of seed, is in the hanger, on the oppositeside ot' said vertical dialneter.

lhus the seeds are received andv discharged on opposite sides ot' the vertical diameter of the seedingcylinder, which prevents the escape ot grain when the seeder is not in operation.

\Vl1atI claim as my invention, and seek to secure by Letters Patent, is-

l. lhe adjustable seeding cylinder, with radial flanges B1, ot` about one-eighth of an inch radius less than the bearing part A ot' the cylinder, or sufficient to allow the grain to pass without crushing, said radial flanges running lengthwise ot the cylinder, substantially as and i'or the purpose specified.

2. In combination with the adjusting seeding-cylinder, above claimed, so arranging the opening U1 for receiving, and the opening C2 for discharging the grain, that the latter shall be received and discharged on opposite sides of' the vertical diameter of the seeding-cylinder, substantially as and for the purpose set forth.
